Negative Power Supply
Power Supply Pins (VDD, VSS)
The positive power supply (VDD) is 2.3V to 5.5V higher
than the negative power supply (VSS). For normal
operation, the other pins are at voltages between VSS
and VDD.
Typically, these parts are used in a single-supply
(positive) supply configuration. In this case, VSS is
connected to ground and VDD is connected to the
supply. VDD will need bypass capacitors.
This is a CMOS, Schmitt-triggered input that places the
MCP618 op amp into a low-power mode of operation.

APPLICATIONS INFORMATION
The MCP616/7/8/9 family of op amps is manufactured
using Microchip’s state-of-the-art CMOS process,
which includes PNP transistors. These op amps are
unity-gain stable and suitable for a wide range of
general purpose applications.

LIMITS
The ESD protection on the inputs can be depicted as
shown in Figure 4-1. This structure was chosen to
protect the input transistors, and to minimize input bias
current (IB). The input ESD diodes clamp the inputs
when they try to go more than one diode drop below
VSS. They also clamp any voltages that go too far
above VDD; their breakdown voltage is high enough to
allow normal operation, and low enough to bypass
quick ESD events within the specified limits.

Protecting the Analog
It is also possible to connect the diodes to the left of
resistors R1 and R2. In this case, current through the
diodes D1 and D2 needs to be limited by some other
mechanism. The resistors then serve as in-rush current
limiters; the DC current into the input pins (VIN+ and
VIN–) should be very small.
A significant amount of current can flow out of the
inputs when the common mode voltage (VCM) is below
ground (VSS). (See Figure 2-36.) Applications that are
high impedance may need to limit the usable voltage
range.
4.1.3

MCP61X
V2
The MCP616/7/8/9 op amp is designed to prevent
phase reversal when the input pins exceed the supply
voltages. Figure 2-36 shows the input voltage exceeding the supply voltage without any phase reversal.
4.1.2
D2
NORMAL OPERATION
The inputs of the MCP616/7/8/9 op amps connect to a
differential PNP input stage. The common mode input
voltage range (VCMR) includes ground in single-supply
systems (VSS), but does not include VDD. This means
that the amplifier input behaves linearly as long as the
common mode input voltage (VCM) is kept within the
specified VCMR limits (VSS to VDD–0.9V at +25°C).
Simplified Analog Input ESD
In order to prevent damage and/or improper operation
of these op amps, the circuit they are in must limit the
currents and voltages at the VIN+ and VIN– pins (see
“Absolute Maximum Ratings †” at the beginning of
Section 1.0 “Electrical Characteristics”). Figure 4-2
shows the recommended approach to protecting these
inputs. The internal ESD diodes prevent the input pins
(VIN+ and VIN–) from going too far below ground, and
the resistors R1 and R2 limit the possible current drawn
out of the input pins. Diodes D1 and D2 prevent the
input pins (VIN+ and VIN–) from going too far above
VDD, and dump any currents onto VDD. When
implemented as shown, resistors R1 and R2 also limit
the current through D1 and D2.

4.2
DC Offsets
The MCP616/7/8/9 family of op amps have a PNP input
differential pair that gives good DC performance. They
have very low input offset voltage (±150 µV, maximum)
at TA = +25°C, with a typical bias current of -15 nA
(sourced out of the inputs).
There must be a DC path to ground (or power supply)
from both inputs, or the op amp will not bias properly.
The DC resistances seen by the op amp inputs (R1||R2
and R4||R5 in Figure 4-3) need to be equal and less
than 100 kΩ, to minimize the total DC offset.

Rail-to-Rail Output
There are two specifications that describe the output
swing capability of the MCP616/7/8/9 family of op
amps. The first specification (Maximum Output Voltage
Swing) defines the absolute maximum swing that can
be achieved under the specified load conditions. For
instance, the output voltage swings to within 15 mV of
the negative rail with a 25 kΩ load tied to VDD/2.
Figure 2-33 shows how the output voltage is limited
when the input goes beyond the linear region of
operation.
The second specification that describes the output
swing capability of these amplifiers is the Linear Output
Voltage Range. This specification defines the
maximum output swing that can be achieved while the
amplifier still operates in its linear region. To verify
linear operation in this range, the large-signal DC
Open-Loop Gain (AOL) is measured at points inside the
supply rails. The measurement must meet the specified
AOL conditions in the specification table.

4.4
Capacitive Loads
4.5
Driving large capacitive loads can cause stability
problems for voltage feedback op amps. As the load
capacitance increases, the feedback loop’s phase
margin decreases and the closed-loop bandwidth is
reduced. This produces gain peaking in the frequency
response, with overshoot and ringing in the step
response. A unity-gain buffer (G = +1) is the most
sensitive to capacitive loads, though all gains show the
same general behavior.
When driving large capacitive loads with these op
amps (e.g., > 60 pF when G = +1), a small series
resistor at the output (RISO in Figure 4-5) improves the
feedback loop’s phase margin (stability) by making the
output load resistive at higher frequencies. The
bandwidth will be generally lower than the bandwidth
with no capacitive load.
MCP618 Chip Select (CS)
The MCP618 is a single op amp with Chip Select (CS).
When CS is pulled high, the supply current drops to
50 nA (typical) and flows through the CS pin to VSS.
When this happens, the amplifier output is put into a
high-impedance state. By pulling CS low, the amplifier
is enabled. The CS pin has an internal 5 MΩ (typical)
pull-down resistor connected to VSS, so it will go low if
the CS pins is left floating. Figure 1-1 shows the output
voltage and supply current response to a CS pulse.
4.6
Supply Bypass
With this family of operational amplifiers, the power
supply pin (VDD for single supply) should have a local
bypass capacitor (i.e., 0.01 µF to 0.1 µF) within 2 mm
for good high-frequency performance. It may use a bulk
capacitor (i.e., 1 µF or larger) within 100 mm to provide
large, slow currents. This bulk capacitor is not required
and can be shared with other analog parts.

Figure 4-6 gives recommended RISO values for
different capacitive loads and gains. The x-axis is the
normalized load capacitance (CL/GN), where GN is the
circuit’s noise gain. For non-inverting gains, GN and the
Signal Gain are equal. For inverting gains, GN is
1+|Signal Gain| (e.g., -1 V/V gives GN = +2 V/V).
4.7
Unused Op Amps
An unused op amp in a quad package (MCP619)
should be configured as shown in Figure 4-7. These
circuits prevent the output from toggling and causing
crosstalk. Circuits A sets the op amp at its minimum
noise gain. The resistor divider produces any desired
reference voltage within the output voltage range of the
op amp; the op amp buffers that reference voltage.
Circuit B uses the minimum number of components
and operates as a comparator, but it may draw more
current.

PCB Surface Leakage
4.9
In applications where low input bias current is critical,
Printed Circuit Board (PCB) surface leakage effects
need to be considered. Surface leakage is caused by
humidity, dust or other contamination on the board.
Under low humidity conditions, a typical resistance
between nearby traces is 1012Ω. A 5V difference would
cause 5 pA of current to flow, which is greater than the
MCP616/7/8/9 family’s bias current at 25°C
(1 pA, typical).
The easiest way to reduce surface leakage is to use a
guard ring around sensitive pins (or traces). The guard
ring is biased at the same voltage as the sensitive pin.
An example is shown below in Figure 4-8.

HIGH GAIN PRE-AMPLIFIER
The MCP616/7/8/9 op amps are well suited to
amplifying small signals produced by low-impedance
sources/sensors. The low offset voltage, low offset
current and low noise fit well in this role. Figure 4-9
shows a typical pre-amplifier connected to a lowimpedance source (VS and RS).

Non-inverting Gain and Unity Gain Buffer:
a) Connect the non-inverting pin (VIN+) to the
input with a wire that does not touch the
PCB surface.
b) Connect the guard ring to the inverting input
pin (VIN–). This biases the guard ring to the
common mode input voltage.
Inverting Gain and Transimpedance gain (convert current to voltage, such as photo detectors)
amplifiers:
a) Connect the guard ring to the non-inverting
input pin (VIN+). This biases the guard ring
to the same reference voltage as the op
amp (e.g., VDD/2 or ground).
b) Connect the inverting pin (VIN–) to the input
with a wire that does not touch the PCB
surface.

High Gain Pre-amplifier.
For the best noise and offset performance, the source
resistance RS needs to be less than 15 kΩ. The DC
resistances at the inputs are equal to minimize the
offset voltage caused by the input bias currents
(Section 4.2 “DC Offsets”). In this circuit, the DC gain
is 10 V/V, which will give a typical bandwidth of 19 kHz.
4.9.2
TWO OP AMP INSTRUMENTATION
AMPLIFIER
The two-op amp instrumentation amplifier shown in
Figure 4-10 serves the function of taking the difference
of two input voltages, level-shifting it and gaining it to
the output. This configuration is best suited for higher
gains (i.e., gain > 3 V/V). The reference voltage (VREF)
is typically at mid-supply (VDD/2) in a single-supply
environment.

THREE OP AMP
INSTRUMENTATION AMPLIFIER
A classic, three-op amp instrumentation amplifier is
illustrated in Figure 4-11. The two-input op amps
provide differential signal gain and a common mode
gain of +1. The output op amp is a difference amplifier,
which converts its input signal from differential to a
single-ended output; it rejects common mode signals at
its input. The gain of this circuit is simply adjusted with
one resistor (RG). The reference voltage (VREF) is
typically referenced to mid-supply (VDD/2) in singlesupply applications.

PRECISION GAIN WITH GOOD
LOAD ISOLATION
In Figure 4-12, the MCP616 op amp, R1 and R2 provide
a high gain to the input signal (VIN). The MCP616’s low
offset voltage makes this an accurate circuit.
The MCP606 is configured as a unity-gain buffer. It
isolates the MCP616’s output from the load, increasing
the high gain stage’s precision. Since the MCP606 has
a higher output current, and the two amplifiers are
housed in separate packages, there is minimal change
in the MCP616’s offset voltage due to loading effect.

DESIGN AIDS
Microchip provides the basic design tools needed for
the MCP616/7/8/9 family of op amps.
5.1
SPICE Macro Model
The latest SPICE macro model for the MCP616/7/8/9
op amps is available on the Microchip web site at
www.microchip.com. This model is intended to be an
initial design tool that works well in the op amp’s linear
region of operation over the temperature range. See
the model file for information on its capabilities.
Bench testing is a very important part of any design and
cannot be replaced with simulations. Also, simulation
results using this macro model need to be validated by
comparing them to the data sheet specifications and
characteristic curves.
5.2
Mindi™ Circuit Designer &
Simulator
Microchip’s Mindi™ Circuit Designer & Simulator aids
in the design of various circuits useful for active filter,
amplifier and power-management applications. It is a
free online circuit designer & simulator available from
the Microchip web site at www.microchip.com/mindi.
This interactive circuit designer & simulator enables
designers to quickly generate circuit diagrams,
simulate circuits. Circuits developed using the Mindi
Circuit Designer & Simulator can be downloaded to a
personal computer or workstation.
5.3
Microchip Advanced Part Selector
(MAPS)
MAPS is a software tool that helps semiconductor
professionals efficiently identify Microchip devices that
fit a particular design requirement. Available at no cost
from the Microchip website at www.microchip.com/
maps, the MAPS is an overall selection tool for
Microchip’s product portfolio that includes Analog,
Memory, MCUs and DSCs. Using this tool you can
define a filter to sort features for a parametric search of
devices and export side-by-side technical comparasion
reports. Helpful links are also provided for Datasheets,
Purchase, and Sampling of Microchip parts.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
